Description

Technical Field

[0001] The present invention belongs to the technical field of emergency repair of gas pipelines, and specifically relates to an integrated emergency repair device for gas pipelines. Background Art

[0002] Due to the aging of the gas supply network, gas pipelines may rupture and leak during use, and emergency repairs must be carried out on site in a timely manner. If the gas pipeline is not seriously damaged, such as a small hole, the saddle repair method can be used without cutting or cutting off the gas pipeline. Before performing gas repair work, the dust and other dirt on the surface of the pipeline must be cleaned, and then the dissolved oxide film on the surface of the pipeline must be scraped off. Then, fix the repair saddle on the damaged gas pipeline, and keep the gas pipeline and the repair saddle in a vertical state. For details, please refer to "Analysis of the Application of Gas Pipeline Emergency Repair Technology" (Zhu Yu. Analysis of the Application of Gas Pipeline Emergency Repair Technology [J]. Process Technology, 2020 (10): 242-243.).

[0003] Referring to the document with the existing publication (announcement) number CN112483754A, an electric fusion saddle pipe fitting for gas pipeline and a processing method thereof are disclosed. The pipe fitting includes a base for connecting with a target pipeline, the base has a saddle-shaped surface that fits with the outer wall of the target pipeline, the saddle-shaped surface is provided with a welding surface for electric fusion welding with the outer wall of the target pipeline, and an electric heating wire is arranged inside the welding surface. The electric heating wire is arranged in a prefabricated electric heating wire ring, and the electric heating wire ring is a disc-shaped plastic part, which is embedded in the saddle-shaped surface by secondary injection molding. The exposed surface of the electric heating wire ring constitutes a part of the saddle-shaped surface, the welding surface is located on the exposed surface of the electric heating wire ring, the base is a ring sleeve structure with an opening, the saddle-shaped surface is located on the inner side of the ring sleeve structure with an opening, the ring sleeve structure with an opening is formed by the closed ring sleeve structure formed by injection molding being disconnected at the opening, and a connecting structure is provided at the opening of the ring sleeve structure, and the connecting structure includes a first connecting part and a second connecting part respectively arranged on both sides of the opening.

[0004] For example, when the above-mentioned electric fusion saddle-type pipe fittings are used to weld and repair pipelines, the base ring structure is put on the target pipeline and tightened, and then the capacitor welding process is performed. The electric heating wire ring is energized to generate heat, causing itself and the upper surface of the target pipeline to melt, thereby welding the electric fusion saddle-type bypass pipe fitting to the target pipeline. However, in the case of continuous gas flow, the high-pressure gas in the target pipeline (i.e., the damaged pipeline) will leak out from the damaged part under the action of pressure, and the ejected gas will be wrapped inside the molten plastic, resulting in pores in the welding area, affecting the sealing and strength of the welding. At the same time, since the molten plastic is fluid and can easily enter the hole, it will cause the inner diameter of the pipeline to become smaller, affecting the fluidity of the gas in the target pipeline. Summary of the invention

[0005] The purpose of this scheme is to provide an integrated gas emergency repair device to solve the problem that the leakage hole of the existing electric fusion saddle type pipe fittings is not blocked during welding.

[0006] In order to achieve the above-mentioned purpose, the present solution provides an integrated gas emergency repair device, including a base and an electric fusion sleeve arranged in the base, and also includes a sealing component, wherein the sealing component is used to cover the leakage hole.

[0007] The principle and effect of this solution are: by arranging a sealing component in the base to cover the leakage hole during welding, high-pressure gas is prevented from leaking from the damaged part and entering the welding area, thereby solving the problem that the existing electric fusion saddle-type pipe fittings cannot effectively block the leakage hole during welding, and ensuring the sealing and strength of the welding area.

[0008] Further, the sealing group includes a baffle, which is arranged in the base, and the baffle is used to cover the leakage hole. The base includes a first base and a second base, the first base and the second base are hinged by a connecting hinge, and the second base and the first base are both provided with threaded holes for locking the first base and the second base, and a locking bolt is provided in the threaded hole of the second base, and the locking bolt is matched with the threaded hole of the first base; the electric fusion sleeve includes a first electric fusion sleeve and two second electric fusion sleeves, the first electric fusion sleeve is arranged in the first base, and the two second electric fusion sleeves are arranged in the second base, and the two second electric fusion sleeves are symmetrically arranged on both sides of the baffle.

[0009] The principle and effect of this scheme are as follows: (1) Since the first base and the second base are hinged by a connecting hinge, it is convenient to quickly open and close the first base and the second base when repairing the pipeline, thereby improving the repair efficiency. (2) The electric fusion pipe sleeve is a prior art, which is provided with a resistance wire. The resistance wire is energized by electric fusion welding to melt the electric fusion pipe sleeve and fuse it with the outer wall of the target pipeline. The second electric fusion pipe sleeve is arranged on both sides of the baffle, so that the molten material of the electric fusion pipe sleeve does not flow to the baffle area, so that the baffle covers and blocks the leak before and after welding.

[0010] Furthermore, the sealing assembly also includes a diverter pipe and a movable rod, the diverter pipe is provided with a through groove and a through hole, the baffle is movably arranged in the through groove, the movable rod passes through the through hole, one end of the movable rod is connected to the baffle, and the free end of the movable rod is arranged outside the second base.

[0011] The principle and effect of this solution are as follows: (1) During emergency repair, in order to improve the efficiency of emergency repair, the first base and the second base need to be closed, and then the locking bolt needs to be turned into the threaded hole so that the first base and the second base will not separate and fall off. However, in order to move the first base and the second base to the position of the leakage hole, it is not necessary to tighten the locking bolt to lock the first base and the second base. However, because the first base and the second base are already closed, it is impossible to locate the position of the leakage hole when moving the first base and the second base, so that the baffle plate presses against the leakage hole. Therefore, when the baffle plate moves to the position of the leakage hole, the high-pressure gas ejected from the hole is used to push the baffle plate and the movable rod to move, so that the free end of the movable rod extends out of the second base. At this time, the emergency repair personnel can observe whether the movable rod is extended to determine whether the baffle plate has moved to the position of the leakage hole. (2) By providing the shunt pipe and the movable rod, the emergency repair personnel can judge whether the baffle has been correctly positioned at the leakage hole by observing the extension of the free end of the movable rod, thereby avoiding the problem of difficulty in locating the leakage hole when the first base and the second base are in the closed state, and enabling the baffle to be positioned at the leakage hole.

[0012] Furthermore, it also includes a cleaning component, which includes a first slip ring and a second slip ring, the first slip ring and the second slip ring are symmetrically arranged at the two ends of the shunt pipe, and the first slip ring and the second slip ring are both slidably connected to the base; the first slip ring and the second slip ring arranged on the first base and the second base are respectively hinged by connecting hinges.

[0013] The principle and effect of this scheme are as follows: (1) When performing emergency repair welding at the location of a pipeline leak hole, it is usually necessary to clean the dust and impurities around the leak hole to prevent the dust and impurities from entering the molten material and causing pores and inclusions. In this scheme, after the emergency repair personnel determine the location of the leak hole, they manually clean the stubborn dust around it in advance, but in order to improve the efficiency of the pipeline repair, the cleaning may not be too careful, and water stains and dust will remain. At this time, move the first base and the second base to the location of the leak hole, and use the high-pressure gas ejected from the hole to enter the diversion pipe, pushing the first slip ring and the second slip ring to move toward each other, so that the slip ring can be used to clean the residual water stains and dust on the pipe wall. (2) This scheme can use the high-pressure gas ejected from the hole to clean the residual water stains and dust around the leak hole without taking up additional operating time for the emergency repair personnel, thereby improving the emergency repair efficiency and welding quality.

[0014] Furthermore, the sealing assembly also includes a wedge tube and a sealing ball, and the number of the wedge tube and the sealing ball are both two. The two wedge tubes are respectively arranged at the two ends of the shunt tube and are respectively connected to the two ends of the shunt tube; the two sealing balls are symmetrically arranged in the shunt tube and are respectively matched with the wedge tube; the sealing ball is connected to a pull rope, and the free ends of the two pull ropes are respectively fixedly connected to the first slip ring and the second slip ring.

[0015] The principle and effect of this solution are: when the first slip ring and the second slip ring move to the limit position, it indicates that the pipeline around the leakage hole has been cleaned. At this time, it is necessary to prevent the leakage hole from spraying gas again to avoid waste. When the first slip ring and the second slip ring move to the limit position, the pull rope is tightened, thereby pulling the sealing ball into the wedge-shaped tube. At this time, the leakage hole is only connected to the diverter pipe, so that the gas will not spray out again.

[0016] Furthermore, two grooves are symmetrically provided in the second base, and the first sliding ring and the second sliding ring are slidably provided in the two grooves respectively; and the length of the pull rope is not greater than the length of the groove.

[0017] The principle and effect of this solution are that the groove provides positioning and guiding functions for the movement of the first slider and the second sliding ring. The length of the pull rope is set so that the sealing ball can be tightened to the wedge-shaped pipe opening when the first sliding ring and the second sliding ring move to the limit position.

[0018] Furthermore, it also includes a locking assembly, which includes two symmetrically arranged gears and racks, the racks are meshed with the gears, the gears are coaxially connected to the locking bolts, and one end of the two racks is fixedly connected to the first slip ring and the second slip ring respectively.

[0019] The principle and effect of this solution are: in order to improve the efficiency of emergency repair, it is necessary to lock the first base and the second base more quickly. This solution uses the gas ejected from the leakage hole to push the first slip ring and the second slip ring to move, thereby driving the gear to rotate, and then the locking bolt is further screwed into the threaded hole, so that the emergency repair personnel only need to tighten and lock the first base and the second base at the end, without performing more bolt rotation work, thereby improving the efficiency of emergency repair.

[0020] Furthermore, the rack is a flexible rack, and the gear is provided with an internal thread that cooperates with a locking bolt.

[0021] The principle and effect of this solution are: the gear is driven to rotate by the rack, the internal thread of the gear cooperates with the locking bolt, and the locking bolt is screwed into the threaded hole in the second base through the rotation of the gear. After welding is completed, the excess rack that protrudes can be cut off.

[0022] Furthermore, a guide rail is provided in the second base, and the rack is slidably arranged in the guide rail.

[0023] The principle and effect of this solution are that the guide rail provides positioning and guiding functions for the movement of the rack.

[0024] Furthermore, the second base is provided with a second groove, the free end of the movable rod is arranged in the second groove, a sealing bolt is arranged in the second groove, and an internal thread matching with the sealing bolt is arranged in the second groove.

[0025] The principle and effect of this solution are: when the baffle moves to the leakage hole position, the free end of the movable rod pushes the nut of the sealing bolt to pop out of the second base, thereby notifying the repair personnel that the baffle has moved to the leakage hole position. After the electric fusion welding, the sealing bolt is tightened into the second groove by turning the nut, thereby pressing the baffle against the leakage hole to prevent the high-pressure gas from expanding the leakage hole again after welding.

DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the concept and technical effects of the present invention in combination with the embodiments, so as to fully understand the purpose, features and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention: Embodiment 1: See also Figure 1 and Figure 2An integrated gas emergency repair device includes a base 1 and an electric fusion pipe sleeve 2 arranged in the base 1. The base 1 includes a first base 11 and a second base 12. The first base 11 and the second base 12 are hinged by a connecting hinge. The second base 12 and the first base 11 are both provided with a threaded hole 13 for locking the first base 11 and the second base 12. A locking bolt 14 is provided in the threaded hole 13 of the second base 12. The locking bolt 14 is arranged in cooperation with the threaded hole 13 of the first base 11. The electric fusion sleeve 2 includes a first electric fusion sleeve 21 and two second electric fusion sleeves 22. The electric fusion sleeve 2 is a prior art. A resistance wire is provided therein. The resistance wire is electrified by electric fusion welding to melt the electric fusion sleeve 2 and fuse with the outer wall of the target pipeline. The first electric fusion sleeve 21 is arranged in the first base 11, and the two second electric fusion sleeves 22 are arranged in the second base 12. The two second electric fusion sleeves 22 are symmetrically arranged on both sides of the baffle 31.

[0029] It also includes a sealing component 3, which includes a baffle 31, a shunt pipe 32 and a movable rod 33. The baffle 31 is used to block the leakage hole, and the baffle 31 is arranged in the second base 12; the shunt pipe 32 is provided with a through groove and a through hole (not shown in the figure), the baffle 31 is movably arranged in the through groove, the movable rod 33 passes through the through hole, and one end of the movable rod 33 is connected to the baffle 31; the second base 12 is provided with a second groove 122, the free end of the movable rod 33 is arranged in the second groove 122, a sealing bolt 37 is arranged in the second groove 122, and an internal thread matching the sealing bolt 37 is arranged in the second groove 122.

[0030] Specific working principle: During emergency repair, in order to improve the efficiency of emergency repair, it is necessary to rotate the first base 11 and the second base 12 to close them, and then rotate the locking bolt 14 into the threaded hole 13 so that the first base 11 and the second base 12 will not separate and fall off. However, in order to move the first base 11 and the second base 12 to the position of the leakage hole, it is not necessary to tighten the locking bolt 14 to lock the first base 11 and the second base 12. Then, move the first base 11 and the second base 12. When the baffle 31 moves to the position of the leakage hole, the high-pressure gas ejected from the hole pushes the baffle 31 and the movable rod 33 to move upward, and the free end of the movable rod 33 pushes the nut of the sealing bolt 37 to pop out of the second base 12, thereby prompting the emergency repair personnel that the baffle 31 has moved to the position of the leakage hole. Finally, after electric fusion welding, the sealing bolt 37 is tightened into the second groove 122 by rotating the nut, so that the baffle 31 is pressed against the leakage hole to prevent the high-pressure gas from expanding the leakage hole again after welding.

[0031] It also includes a cleaning component 4, which includes a first slip ring 41 and a second slip ring 42. The first slip ring 41 and the second slip ring 42 are symmetrically arranged at the two ends of the shunt pipe 32, and the first slip ring 41 and the second slip ring 42 are both slidably connected to the base 1. Two grooves 121 are symmetrically arranged in the second base 12, and the first slip ring 41 and the second slip ring 42 are slidably arranged in the two grooves 121 respectively; the first slip ring 41 and the second slip ring 42 arranged on the first base 11 and the second base 12 are respectively hinged by connecting hinges. The sealing assembly 3 also includes a wedge tube 34 and a sealing ball 35. The number of the wedge tube 34 and the number of the sealing ball 35 are both two. The two wedge tubes 34 are respectively arranged at the two ends of the shunt tube 32, and are respectively connected to the two ends of the shunt tube 32; the two sealing balls 35 are symmetrically arranged in the shunt tube 32, and are respectively matched with the wedge tube 34; the sealing ball 35 is connected to a pull rope 36, and the free ends of the two pull ropes 36 are respectively fixedly connected to the first slip ring 41 and the second slip ring 42, the length of the pull rope 36 is not greater than the length of the groove 121, and the pull rope 36 is made of metal that will not be electrofused. The locking assembly 5 also includes two symmetrically arranged gears 51 and a rack 52. The rack 52 meshes with the gear 51. The gear 51 is coaxially connected to the locking bolt 14. One end of the two racks 52 is fixedly connected to the first slip ring 41 and the second slip ring 42 respectively. A guide rail is provided in the second base 12. The rack 52 is slidably arranged in the guide rail. The rack 52 is a flexible rack 52. The gear 51 is provided with an internal thread that cooperates with the locking bolt 14. The gear 51 is driven to rotate by the rack 52. The internal thread of the gear 51 cooperates with the locking bolt 14. The locking bolt 14 is tightened in the threaded hole 13 in the second base 12 through the rotation of the gear 51.

[0032] Specific working principle: After the emergency repair personnel determine the location of the leakage hole, they manually clean the stubborn dust around the leakage hole in advance. Then, move the first base 11 and the second base 12 to the location of the leakage hole, and use the high-pressure gas ejected from the hole to enter the shunt pipe 32 to push the first slip ring 41 and the second slip ring 42 to move toward each other, so as to use the first slip ring 41 and the second slip ring 42 to clean the residual water stains and dust on the pipe wall. When the first slip ring 41 and the second slip ring 42 move, the rack 52 is pushed to move, thereby driving the gear 51 to rotate, and then the locking bolt 14 is further screwed into the threaded hole 13, so that the emergency repair personnel only need to tighten and lock the first base 11 and the second base 12 at the end, without performing more bolt rotation work, thereby improving the emergency repair efficiency. When the first slip ring 41 and the second slip ring 42 move to the extreme position, it indicates that the pipeline around the leakage hole has been cleaned. After the first sliding ring 41 and the second sliding ring 42 move to the limit position, the pull rope 36 is tightened, thereby pulling the sealing ball 35 into the wedge-shaped tube 34, so that the gas will not spray out again.

[0033] Embodiment 2: The difference between this embodiment and the previous embodiment lies in the structural arrangement of the sealing assembly 3 .

[0034] See also Figure 3-Figure 6 The sealing assembly 3 includes a first sleeve 38, a second sleeve 39, a third sleeve 310 and a fourth sleeve 311 arranged in the second base 12. The first sleeve 38, the second sleeve 39, the third sleeve 310 and the fourth sleeve 311 are all provided with a slide groove 312. The second sleeve 39 is slidably arranged in the slide groove 312 of the first sleeve 38, the third sleeve 310 is slidably arranged in the slide groove 312 of the second sleeve 39, and the fourth sleeve 311 is slidably arranged in the slide groove 312 of the third sleeve 310. The inner diameters of the first sleeve 38, the second sleeve 39, the third sleeve 310 and the fourth sleeve 311 decrease in sequence, so that the first sleeve 38, the second sleeve 39, the third sleeve 310 and the fourth sleeve 311 form a telescopic structure. Among them, the second sleeve 39 is provided with an exhaust passage 391 (see Figure 6 As shown by the arrow, the air inlet end of the exhaust passage 391 is connected to the leakage hole, and the air outlet end of the exhaust passage 391 is arranged above the pipe wall of the target pipe. After the second sleeve 39 is retracted into the first sleeve 38 and the third sleeve 310 is retracted into the second sleeve 39, the air inlet end and the air outlet end of the exhaust passage 391 are respectively closed by the second sleeve 39 and the third sleeve 310, so that the air inlet end of the exhaust passage 391 is cut off from the leakage hole, and the air outlet end of the exhaust passage 391 will not spray gas onto the pipe wall of the target pipe. Further, the length of the first sleeve 38 is equal to the pipe wall thickness of the target pipe, and the leakage hole is sealed after the second sleeve 39, the third sleeve 310 and the fourth sleeve 311 are retracted. The first sleeve 38, the second sleeve 39, the third sleeve 310 and the fourth sleeve 311 are all made of metal materials that are not electro-fused to avoid electro-fusion of the leakage hole.

[0035] Specific working principle: After the emergency repair personnel determine the location of the leak hole, they manually clean the stubborn dust around the leak hole in advance. Then the first base 11 and the second base 12 are moved to the vicinity of the leak hole, and the first sleeve 38, the second sleeve 39, the third sleeve 310 and the fourth sleeve 311 are moved to the location of the leak hole. The gas ejected from the leak hole enters from the air inlet end of the exhaust tunnel 391 and is ejected from the air outlet end of the exhaust tunnel 391, thereby changing the gas originally ejected upward from the leak hole to horizontal lateral ejection, and then using the ejected high-pressure gas to clean the dust remaining around the leak hole, so that the melted material of the electric fusion pipe sleeve 2 fits with the pipe wall of the target pipe to reduce inclusions. Then, the repair personnel press the second base 12, so that the first sleeve 38 is inserted into the leakage hole, the second sleeve 39, the third sleeve 310 and the fourth sleeve 311 are retracted in sequence, the air inlet end and the exhaust end of the exhaust passage 391 are sealed, and the first sleeve 38, the second sleeve 39, the third sleeve 310 and the fourth sleeve 311 are folded into a closed cylinder, and the height of the cylinder is equal to the pipe wall of the target pipeline, so as to seal the leakage hole. Then, the first base 11 and the second base 12 are locked with the locking bolt 14, and finally the electric fusion sleeve 2 is electro-fused with an electric fusion welding gun.

[0036] The above are only embodiments of the present invention, and the common knowledge such as the known specific structures and characteristics in the scheme are not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
